T0 allwhomit may concern:

Be it known that-I, SEWELL A. KNAPP, a citizen of the United S tates,;residing at city and county of San Francisco and State of California, have invented a new and useful Improvement in Composite Barrels, of which the following is a specification.

This invention relatesfto a barrelcons truction and particularly pertains to. a composite knock down barrel. v

It is the principal object of the present invention to provide a barrel which may be cheaply made while withstanding rough usage and which will satisfactorily preserve the contents-of the barrel from the action of air and moisture, said barrel being so constructed as to bereadily knocked down when empty.

The invention contemplates the use of special barrel heads comprising a ring rolled from sheet metal to form a croze adapted to receive a separable wooden head, said sheet metal ring being further designed so as to receive, a chine ring which rests upon the wooden head, said head rings being readily assembled in connection with wooden barrel staves by which an air tight composite barrel is completed.

The invention is illustrated by way of ex ample in 'the accompanying drawings, in which:"

Fig. 9 is a view in transverse section showing the joint between the contiguous ends of the barrel as constructed in the manner shown in Fig- 8. v

In the drawings, 10 indicates the body of a barrel. This structure may" be either designed on the lines of a straight or a bilge barrel and is formed by a plurality of staves-11. The ends ofthesestaves arecut off square" and rest against shoulders 12 formed as a part of head rings 13.- These.

rings are adaptedto be detachably secured to the oppositeends of the staves. The drum rings are rolled fromsheet metal of desired gauge and are formed with a cylindrical portion 14 having a V-shaped circumferential groove or rib15 therearound. This rib extends-into a \/'-shaped seat '16 formed across'each of the staves: The opposite end of the cylindrical portions'lat of the rings are formed with outwardly rolled croze members 17. This portion of the ring'is adapted to lie within the line, of the outer face of the staves and thus make it possible to readily remove the" barrel ,hoops 18. An annular chine seat 19 is formed by the outer marginal edge of the ring 13 and isladapted to receive a chine ring'20. 7 This chine ring may he of any desired construction and may be of any'sectional formation. InFig. 5 it is shown as being circular, and in 7 as being rectangular in section. The chinering is directly disposed-aroundthe mouth of the barrel and on top of the barrel heads,

thus insuring that anyexternal forces actmg along the chine ring and thereagalnst would be'transmitted to thebarrel head and thento the fends of the staves and wouldbe absorbed withoutdamageto the complete structure and particularly to the inner drum r hoops may, undersome conditions be ,C

bilge barrel all of the rings may be driven into position although other forms of barrels might require the structure shown in Figs. 3 and 4:. r

In the form of the invention shown in Figs. 6 to 9 inclusive, the barrel is slightly reconstructed so that an interior container may be enclosed within the wooden barrel structure. This makes it possible to transmit liquids within a container of very light gauge metal, the wooden protecting barrel taking up the shock and which may be removed and replaced, so that repairs can be easily made to the inner drum.

It is also possible to knock down the metal barrel when constructed as shown in Figs. 8 and 9. This is preferably done by forming the head rings as previously described and providing means whereby they may be directly mounted upon the opposite ends of a collapsible metal barrel body 25. This member is formed with a single piece of sheet metal rolled in the shape of a cylinder and being brought together with a joint as shown in Fig. 9. This oint comprises an overlapping V-shaped portion 26 between the sides of which contiguous edge of the barrel sheet metal may be seated. A tight joint is formed folding the packing strip 27 around. this edge and wedging the edge with the strip into the ll-shaped flange 26. It is preferable that this packing member shall be of fabric treated with tar, )aratfine. or other material impervious'to moisture. The end construction of the barrel member 25 comprises an outwardly rolled and circumferentially ex tending t -shaped groove 28 adapted'to be set around the V-shaped ribs 16 of the head rings. The marginal edges of the ,metal. at the ends of the barrel are beaded and are preferably turned over a reinforce ing wire. The barrel body is positively held in its assembled position relative to the head rings by means of hoops 29. These hoops are also V shaped in cross "sec tion'to provide a seat for the ribs 28. The hoops are held in position by a clamping mechanism similar to that shown in Figs. 3 anal.

The cross portions 17 at the opposite endsot the barrel are adapted to receive wooden heads20. These heads ar'e' preferlt may also be convenient to pro-- that downward pressure upon the sections and 34 will firmly seal the various sections oi: the head relative to each other. This sealing operation is brought about by a lever piece which is secured tothe outer face of one of the members 33 and overhangs the other member 34:. A. fastening wire 36 is mounted upon the free end of the lever piece 35 and provides means whereby the wire and a staple 37 may be secured together by a wire or any other suitable look. I

In the operation and use oi the barrel structure shown in Fig. l, the variousstaves 11 are formed and in this connection it might be stated that by utilizing stock staves. the grooved ends of which may be sawed off, the present structure may be used to produce a barrel of the'same size and capacity, as though the st'aves were used in the construction of the ordinary barrel. The staves after having been formed with the transverse grooves 16 are then ready to be arranged around the cylindrical portions 1% of the head. rings. It is to be understood that the head rings are permanently formed in their annular positions and are not supposed to be knocked down. After the staves have been properly placed around the rings, hoop 11 may be driven into position or clamped as previously explained. It will be understood that the chine rings 20 will be permanently placed within the head rings and that the head members 32 to '34 inclusive, may now be disposed in proper position. When the member 35 is fastened down to the member 34;, the barrel will be completely sealed and may be very conveniently used in transporting dry, loose material such as'cementandthe like. In the form of the device shown in Figs. 6 and 7. thesame'com struction is carried out with the additional use of the inner lining 24. With this construction the barrel may be filled with liquids or semi solids and transported from place to place without danger of leakage and at the same time with the assurance that the outer wooden barrel will protect the light metal from the harmful blows and crushing strains which would otherwise be disastrous.

readily nested in a small-space.

While l hav'eshown the preferred form ot my invention as now known to me, it will he plurality of barrel sheets or staves may beunderstood that various changes in the construction, combination and arrangement of parts may be made by those skilled in the art Without departing from the spirit of the invention as claimed.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is: 1
